VAPOR-GENERATION AND POWER SYSTEM.

Toall whom it may coricem:

Be it known that 1, Farmers X. GOVERS, a citizen of the United States,residing at Owego, in the county of Tioga and State of New York, haveinvented. certain new and useful Improvements inVapor-Generation andPower Systems, of which the following is aspecification.

My invention relates generally to systems and processes for theproduction of power, but it has particular reference to the productionof vapors of volatile liquids foruse in power generating apparatus.

The purpose of the invention is to produce a system and process ofgenerating power whichwill be characterized by high efiiciency andabsolute safety.

In pursuance of this object, my invention consists in the employment ofa liquid having a boiling point lower than that of water and preferablyat or less than 80 C. and from which there may be produced an expansiblevapor which can be effectually used as a motive force and which vapor isfurther characterized by non-inflammability and lubricating properties.I have discovered that tetrachlorid of carbon, (C01 possesses theseproperties in a maximum degree, and, my invention, therefore, furtherconsists in the utilization of said material in the generation of motivepower and for lubricating purposes. Said material is inexpensive. It isa heavy liquid which boils at. temperatures variously given by theauthorities as between 76 C. and 78C. It has a specific gravity at 0 of1.6298. Its vapor has a density of 5.24 and is non-inflammable: and,moreover, according to my discoveries, it effectually lubricates thesurfaces with which it is brought in contact and,

being a vapor, it enters and lubricates spaces which paratus suitablefor use in the generation and utilization of said vapor. In saiddrawing, A designates a generator of any suitable constructionwithinwhich the vaporizable liquid, as tetrachlorid of carbon, is placed. Saidgenerator may be provided with tubes 0 which are immersed in saidmaterial and through which flow steam or other suitable medium forraising the temperature of the material to or above its boiling point.From the vapor chamber or portion a of said generator a pipe a leads thevapor to the supply or inlet port I) of a motor 13' which may be of theordinary steam engine type or of any other suitable construction. Afteracting by its expansive force on the piston of said engine andlubricating the same andthe wall of the cylinder, the exhaust. vapor isconducted by the exhaust pipe b to a condenser C within which it iscondensed. It is then conducted by a pipe (2 to a suitable Specificationof Letters Patent.

pump D by which it isforced back to the generator through a pipe (1 forre-use.

Among the advantages-possessed by the present invention, the followingwill be noted. The vapor possesses the necessary expansive force orelasticity and tension to be efiectiveas a power medium. It possesses insuch respects the qualities of steam, while, as the material boils at atemperature much lower than that of water, its vapor may be producedmore economically in respect'of the heat used than can steam. Again, itis capable of being used in ordinary steam engines, whereby itsutilization is attended with the advantages which flowfrom'the use ofsuch engines, while, at the same time, being non-inflammable, iteliminates the dangers which follow the use of volatile liquids hithertoproposed for use in power systems. Thus it possesses the advantages ofboth steam and highly volatile liquids heretofore proposed with thedisadvantages of neither, and, moreover, having lubricating propertiesof high efliciency', it has an additional advantage, not possessed byeither steam or other systems hitherto employed.

In power systems heretofore employed wherein the vapor of a highlyvolatile liquid is utilized in the productionof power and condensed forre-use, it has been found that the liquid-becomes contaminated by thematerial employed in lubricating the engine cylinder and such material,unless removed, seriously interferes with the operation of the system.Great difficulty has been experienced in satisfactorily removing suchlubricating material from the liquid used for the generation of power.It will be seen that these disadvantages are overcome by the utilizationof a volatile liquid, as hereinbefore described, which is itself alubricant.

Inaddition to the properties hereinbefore' set forth, the vapor oftetrachlorid of carbon possesses the property of rendering inflammablevapors with which it is brought in contact non-inflammable. Thisproperty is of marked advantage in a liquid for-the purpose specified,for the reason that it permits volatile liquids, such as naphtha, vaporsof which are highly inflammable, to be safely used in conjunction withit. It is to be understood, therefore, that l contemplate as withinthepurview of my invention not only tetrachlorid of carbon alone, but saidmaterial with other highl'yvolatile liquids whose use has heretoforebeen exceedingly dangerous by reason of the great inflammabilit y andexplotability of their vapors.

Having thus described the invention what I believe to be new and desireto secure by Letters Patent, is:-

1. A system for generating power, comprising a vapor generator, :1 motoradapted to utilize the expansive force of the vapor, and a condenser,suitably connected in a closed circuit, said closed circuit containingtetrachlorid of carbonand its vapor.

Q sews?- 27 In a system for generating power, a vaporizable liquid whosevapor is non-inflammable and adapted to actuate and lubricate the movingparts of a motor, said liquid comprising tetrachlorid of oar-hon.

3. The process of generating a .gaseous vapor for power and lubricatingpurposes, which consists in inciosing tetra:

chlorid of oarbon in a chamber, heating said tetrachlorid of carbon to atemperature at or above its boiling point, conducting the vapor thusproducedinto a motor and ber for re-use..

In testimony whereof I aflix my signature in presence of two witnesses.j
